Perfect Secrecy in IoT: A Hybrid Combinatorial-Boolean Approach

Perfectly-secure cryptography is a branch of information-theoretic cryptography that guarantees that the malicious third party cannot guess anything regarding the plain text or the key, even in the case of full access to the cipher text. This book presents a hybrid combinatorial-Boolean model for perfectly-secure cryptography in IoT, which is organized in two parts. The first part studies information-theoretic cryptography and the promise it holds for cryptography in IoT, while the second part discusses combinatorial and Boolean cryptography and presents the hybrid combinatorial-Boolean model for perfect secrecy.

Perfectly-secure cryptography is a subfield of information-theoretic cryptography that ensures that even with complete access to the ciphertext, an evil third party cannot deduce anything about the plaintext or the key. Despite this benefit, there are only a handful of real-world implementations of perfect secrecy due to some well-known constraints. Any straightforward, intuitive modelling can pave the way for further advancements in the implementation, particularly in environments with time and resource constraints such as the Internet of Things (IoT). This book takes one step towards this goal by presenting a hybrid combinatorial-Boolean model for perfectly-secure cryptography in IoT.

In this book, we first provide an introduction to information-theoretic cryptography, as well as perfect secrecy and its real-world implementations. Then, we take a systematic approach to highlight information-theoretic cryptography as a convergence point for existing trends in research on cryptography in IoT. Next, we investigate combinatorial and Boolean cryptography and show how they are almost ubiquitous in the ecosystem and the life cycle of information-theoretic IoT cryptography. Finally, we model perfect secrecy in IoT using Boolean functions and map the Boolean functions to simple, well-studied combinatorial designs like Latin squares.

This book is divided into two parts. The first part studies information-theoretic cryptography and the promise it holds for cryptography in IoT. The second part discusses combinatorial and Boolean cryptography separately, and then presents the hybrid combinatorial-Boolean model for perfect secrecy in IoT.
